DÄ internationalArchive36/2010Important Study Should Have Been Considered
LNSLNS

In addition to the article by Schmidt et al (1) we would like to point out that the first and so far only controlled study on this subject was published in Germany in 2007 (2). Our study included 502 patients and is one of the largest investigations on telemedically supported healthcare services in patients with chronic heart failure.

Mortality data from our study were used for calculating effect sizes in a 2009 review article in the renowned Journal of the American College of Cardiology (3).

Analysis of our data by intention to treat confirmed a significant drop in mortality (24.9% versus 32.5%, P=0.007) and a significant reduction in hospital days (by 37.5, P/0.025) in the intervention group (telemonitoring and telecoaching) compared with conventional care after 24 months. These results were presented at the 2009 fall meeting of the German Society of Cardiology (4).
